EN 480-13:2009/FprA1

Overview

EN 480-13:2009/FprA1 is a European standard developed by CEN (European Committee for Standardization) that focuses on admixtures for concrete, mortar, and grout. Specifically, this standard outlines test methods for creating a reference masonry mortar designed to evaluate mortar admixtures as defined in EN 934-3. The document prescribes the constituent materials, composition, and precise mixing procedures to produce a masonry mortar with a controlled consistence ideal for testing purposes. Additionally, it includes methods to determine the water reduction effect of various mortar admixtures compared to a control mix.

This standard amendment updates certain requirements related to cement properties, such as its specific surface area, ensuring consistency and relevance in testing procedures.

Key Topics

• Reference Masonry Mortar Composition
  Specifies constituent materials and their precise proportions for creating a standardized masonry mortar mixture.

• Mixing Procedure
  Defines a uniform mixing process to ensure reproducible mortar consistency for testing mortar admixtures.

• Testing Mortar Admixtures
  Provides test methods aligned with EN 934-3 to evaluate the performance of admixtures, focusing on workability and water reduction.

• Water Reduction Measurement
  Describes procedures for measuring how much water the admixture can save compared to a control mortar mix, an important factor for both performance and sustainability.

• Cement Specification Update
  Adjusts the required specific surface area for cement used in the reference mortar mix from 3,200-4,000 cm²/g to 3,600-4,600 cm²/g as measured per EN 196-6, ensuring improved material consistency.

Applications

EN 480-13:2009/FprA1 serves as a foundational test method standard in the construction and material science industries with practical applications such as:

• Quality Control in Admixture Production
